Teal 1401mm it may concern: I

Be a it known that I, HENRY EIsnLn, a citizen of; the; United States, a, resident of Dec atur in the county of Maconiand. State of Illinois, have invented {a oertain I new and useful Quartering Device for Locomotive Wheels, of which the following is a specification The invention relates to; improvements. in devices for quartering driving; wheels of locoiinotives and the like, to provide a simple practical and efiicient device of Strong and comparatively. inexpensive constrr ,tion

adapted torberrea-dily 'appliedito the driving wheels,; of an axle of a, locomotive, and

capable. of readyadjustment to. suit the diameter of the wheeland the depthof thecenter opening and of enabling the relative angular position of the wrist pinslto be easily, quickly anideccurately determined.

lVithlthe present style of locomotive driving, wheeliquartering devices, it i$,- impossible to read the gauge in variations of degrees and it is an object of the present invention to ,providea locomotivedriving wheel quartering device adapted, shouldthe readings of the device when applied to the driving wheels of an axle not exactly total 90to indicatethe amountof the variation in: degrees and fractions of degrees.

To the accomplishment of} the foregoing, and such other objects as may hereinafter appear, my invention consists in the construction, combination and arrangement of parts hereinafter described andithen sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof and which show, merely for the purpose of illustrative disclosure, a preferred embodiment of my invention, it being expressly understood,

howevenvthat variations may be made in practice within the scope of,the claims without digressing from my inventive idea.

In the drawings:

Figure 1 represents an, elevational View of a locomotive drive wheel with a device constructed according to my invention shown in use.

Referring particularly to Figures 1 m4 inclusive of the drawings 1 designatesa driving wheel having a wrist pinj iZ, and mounted on an axle 3 which is provided with theusual center hole, Inthe case ofv loco-- motives,- the. wrist pins: on the. opposite wheels; of; an axle are maintained at an angle of 9 0 relative toeach other. This relative position may be disturbed I through wear anditearof operation and the devicef of, the presentinvention will: quickly, indicate whether or not the wheels are properly positioned 'Ilhedvice is'also adapted for testing the position of the wheels when renewing the, axle or; a-wheel orv wheels andiin pressing-the same ontheends of the axle.

'llh'e device, comprises in its: construction,; 3 a squared ban 4, provided at its upper end with integral vangularly. disposed arms 5 forming a forked or- V-shaped member or yoke; having the edge 6' at the junctionof the said arms 5=adapted to fit against the wrist pin 2 in positioning the device on awheel. Securedtoflthebar 4L, which constitutes the body of the device, is a circular base plate 7, preferably. attached to the upper portion of a bar, 4 by screws 8,.butthe base plate which constitutes-theback of-the indicating meansmay be made rigid with: the bar 4 in any other desired mani'ier; Mounted on' the circular. relatively. fixed member ,is a rotary member consisting of an, adjustable wheel composed of inner and outer; circularv sections 9 and 10 and secured. together by. screws 11 arranged vat spaced pointsadjacentthe peripheries of the inner and outer: sectionsof the rotary member, The inner; section 9., which is circular, consistsof a flatdisk constituting a dial and provided with a central inwardly or rearwardly projecting cylindrical bossl12, con-- stitntinga: journal and fitted in .a central bearing opening 13' in they fixed circular member 7, asiclearly illustrated in Fig.3 of

the drawin s. The central journal 12 is provided with a reduced threaded portion 14 on which is mounted a washer 15, a nut 16 which engages the washer and maintains the tension adjustment of the same against the central bearing portion 17, of the fixed member 7 and a lock nut 16 which locks the adjustment of nut 16. The washer which is assembled over the threaded por tion 14 is locked in position against rotary movement by pin or key. The bearing portion 17, is arranged at the rear face of the fixed member 7 and the latter is provided at its front face with central and circumferential bearing portions 18 and 19, which receive corresponding bearing portions 20 and 21 of the inner section 9 of the rotary adjustable member. The relatively fixed member 7 and the inner section 9 of the rotary member are recessed or cut away to provide a clearance 21, between the central and circumferential bearing portions for reducing friction to a minimum. The inner section 9 of the adjustable rotary member is provided with an inwardly extending peripheral flange 23 which fits in a corresponding annular recess 24 of the said rib 22. The said inner section 9, extends circumferentially beyond the outer section and is bevelled at the outer face of the circumferential portion at 25, the bevelled face being graduated to provide a scale. The graduations of the scale preferably start at Zero and run to 90 in each direction and then extend again to. zero, two series of such graduatlons being thus provided so.

The indicating hand or pointer which is located within the rotary adjustable member is provided with a weighted lower portion 29 and is mounted on cone pivots 3O and'31 carried by the inner and outer sections 9 and 10 of the rotary adjustable member. The cone pivot 30 which consists of a head and a reduced shank is mounted in a central portion 32, in the inner section 9 which is counter-bored to receive the head of the cone pivot 30. The head of the cone pivot 30 is seated against the shoulder formed by the counter-bore of the inner section 9 of the rotary adjustable member. The cone point 31 is mounted in a central bore 33 of outer section 10 which is counterbored and threaded at the outer portion of the said bore 33 to receive the threaded end of cone pivot 31, the thread on cone pivot 31, which is provided as a means of adjustment, is locked in position by the nut 34. The indicating hand or pointer is provided with central bearings at its inner and outer face preferably formed by a small bore extending entirely through the hand or pointer and slightly enlarged at the terminals to receive the cone pivots. By this construction, the indicating hand or pointer is exceedingly sensitive and binding of the same within the rotary adjustable member is efl'ectually prevented. Also the pivots may be readily adjusted to compensate for any wear of the parts. The outer section is provided with a side aperture 35 located at the u per portion of the said outer section ant adapted to uncover the upper end of the indicating hand or pointer and the hair line 26, in any position the hand or pointer may assume by reason of the position of the wrist pin of a driving wheel. The rotary adjustable member is provided with a hair line 36, which is adapted to be brought. into register or alignment with the hair line 26 of the indicating arm or pointer and areading of the quartering gauge is taken from the bottom of the adjustable member, the Vernier gauge 28 being adapted to afford a division of degrees into tenths as will be readily understood.

The bar 4 receives an adjustable block 37 carrying an axle engaging member 38 and provided with an opening 39 of substantially rectangular form to present smooth side faces or walls to the side faces of the bar 4 and cut away at the corners at 40 and 41, to prevent the corners of the bar from contacting with the walls of the opening of the block. This construction by providing corners clearances, enables the block to slide on the bar 4 with a minimum amount of friction. The block is provided at the front with a set screw 42 threaded into the block and arranged to engage the bar 4. for clamping the slidablc block 37 in its adjustment. The block is provided at its upper portion with spaced aligned guides 43 and 44, formed integral with the block and having aligned openings for the reception of spaced parallel rods 45 which constitute a part of the axle engaging member 38 and which are connected at one end with the head of the same. The rods 45 are mounted at opposite sides of the bar 4 and they tirin- 1y support the axle engaging head or portion 38 in a central position with relation to the axis on the bar 4. The guides 43 and 44 project laterally from the block and the guides 44 are split at the bottom by means of a kerf 46 to form resilient clamps for engaging the rods 45 to maintain the axle engaging member in its adjustment. The block is provided at the guides 44 with a transverse opening 47 receiving a clamp ing screw 48 provided at one end with the head and threaded at the other end to engage. a threaded part of the opening 47.

iii)

The opening 47 is threaded at one end beyond one of the kerts l6 and the head of the screw engages the guide ist at the outer side of the other k'ert 4'6. By this construction, the rods 45 may be clamped in their adjnstinent. The axle ei'igaging member 38 which fits in the center opening of the axle, consists ota. ball head and the saic rods 45'. A head of the axle engaging-meniber is preferably rounded or semi-spherical at the outer portion and has a polygonal inner portion with which the rods are connected'. By adjusting the screws 42 and 48, the axle engaging device may be readily arranged at the desired distance from the yoke to fit in the center opening of the axle and. the axle engaging device may also be moved inwardly and outwardly with respect to the bar I} to correspond with the depth of the center opening of the axle.

The indicating means consisting of the pivoted pointer or hand 27 may be varied in construction and instead of employing a hand as shown in Figs. 1 to el inclusive, therotary adjustable device may be equipped with a level n) having a bubble tube as illustrated in F 5 and if desired the indicating means may consist of a disk 50 weighted at the lower portion at 51 for maintaining its indicating means in a vertical position. In each instance thereadings are taken at" the bottom of the rotary adjustable member and vernier scales will,

in practice he provided for each quarter-ing au In the use of the quartering gauge, the device is applied" to one 0% the wheels of an axle by fitting the axle engaging; member in the central opening of the axle and the yoke against the wrist pin of the drive wheel" and the reading is taken at the bottom ofthe rotary adjustable men'iber. The device is then transferred to the other driving wheel of the axle and the position of the wrist pin. is. found in the same manner and. if the sum of two readings is 90, the wrist pins will, be in proper position, but if there should be any variation between 90 and the actual position of the wrist pins, the variation. will. be indicated in degrees and fractions of a degree by the, Vernier scale.
